This patch series extends kwbimage v0 format support by providing
ability to dump content of Dove boot images (extension of v0 format).
It also fixes recognition of these images in kwboot utility (as it uses
macros and inline functions from kwbimage.h header file).

Implementation is based on 88AP510 Functional Specifications,
Chapter 5.2 Boot Image Format, which is publicly available at:

Printing information about image.kwb is possible by:

  $ ./tools/dumpimage -l image.kwb

Dumping image.kwb is possible by commands:

  $ ./tools/dumpimage -T kwbimage -p -1 -o image.cfg image.kwb
  $ ./tools/dumpimage -T kwbimage -p 0 -o data.bin image.kwb
  $ ./tools/dumpimage -T kwbimage -p 1 -o binary1.bin image.kwb
  $ ./tools/dumpimage -T kwbimage -p 2 -o binary2.bin image.kwb
    (where -p N is Nth binary executable header, e.g. SPL)

Dove images contains more sections which in config file begins with line
"MATCH ADDRESS 0xaddr MASK 0xmask VALUE 0xval" and means that section is
executed only when check ((readl(addr) & mask) == (val & mask)) passes.

Support for generating these kind of images is not provided.
I hope that this patch series helps somebody else to implement it.
